Acknowledgment

These Ferredoxin I & III models are based upon the coordinates of [2Fe-2S] Ferredoxin of Spilulina platensis. The models were constructed with the method called ProMod at SWISS-MODEL and refined with CHARMm. SWISS-MODEL is an Automated Protein Modelling Server running at the Geneva Biomedical Research Institute, Glaxo Wellcome Research and Development S.A., Switzerland.
